Abstract: PURPOSE:To easily grow the titled semiconductor having excellent crystallinity with good controllability by simultaneously sending a gaseous org. compd. contg. Fe as the material for dopant and the equal or higher amt. of a gaseous halide into a pipe for introducing the gaseous org. compd. CONSTITUTION:The gaseous org. compd. contg. Fe [e.g., biscyclopentadienyl iron (expressed CP2Fe hereunder)] as the dopant material and the gaseous halide (e.g., HCl) are sent into the introducing pipe 13 in the halide-transporting vapor phase growth method for a III-V compd. semiconductor. In this case, the amt. of the gaseous halide is made equal to or higher than the amt. of the gaseous org. compd. to be supplied. The CP2Fe is thermally decomposed, and the iron reacts with the HCl to form FeCl2. Even if liq. FeCl2 is formed, the vapor of FeCl2 has an extremely high pressure of >=250Torr at <=900 deg.C, and hence the FeCl2 is immediately vaporized. The iron element is transported onto a substrate, and a semi-insulating compd. semiconductor is obtained. An iron reaction chamber and its heating furnace which have been used in the conventional technique can be dispensed with, and the titled semiconductor having excellent crystallinity is obtained.

Title: Power source noise eliminating circuit
Inventor: SAKAIDA YOUSUKE
IPC: H03F3/20
Filed: 1983-05-04
Abstract: PURPOSE:To cancel mutually a noise component, and to raise a power source noise eliminating ratio by superposing that of an opposite phase to a power source noise component superposed in advance on the middle point potential VM, on an input signal. CONSTITUTION:When an input signal source VIN is applied, it passes through an AC component C2, and since a potential which has divided VSS by R1 and R2 exists in a point 7, an input VIN1 is applied equivalently to an LSI input. When an AC portion of an equivalent input component 1/2-VN of a power source noise VN by a middle point potential VM is taken into consideration, an equivalent AC input component VINAC of the whole becomes as shown in an expression I . Accordingly, in case of R1=R2, in the expression, the second and the third terms (noise portions) are cancelled each other, VINAC becomes VINAC= VIN, and the influence by the power source noise is eliminated. Also, an input impedance Zin which has counted on an LSI side from the point 7 connects in parallel R1, R2 and R3, and an expression II is valid. Accordingly, the power noise can be eliminated by setting the values of R1, R2 and R3 so that the expression I and the expression II are valid.
